ATI Fluid and Electrolytes Questions
Question 1 of 5
The term used to describe a blood sodium level of more than 145 mEq/L is:
Correct Answer: C
Rationale: The correct answer is C: hypernatremia. Hypernatremia refers to an elevated level of sodium in the blood, specifically when it is more than 145 mEq/L. Choice A, hyponatremia, is incorrect as it refers to low sodium levels. Choice B, hyperkalemia, is incorrect as it refers to high potassium levels, not sodium. Choice D, hypercalcemia, is also incorrect as it relates to elevated calcium levels, not sodium.
Question 2 of 5
What fluid is found in spaces between the cells?
Correct Answer: B
Rationale: The correct answer is B, Interstitial fluid. Interstitial fluid is the fluid that surrounds and occupies the spaces between cells, providing them with nutrients and removing waste. Choices A, C, and D are incorrect because intracellular fluid refers to fluid inside cells, plasma refers to the liquid component of blood, and electrolyte refers to substances that dissociate into ions in solution, affecting fluid balance but not specifically found in spaces between cells.
Question 3 of 5
Which hormone is made in the pituitary gland and increases water absorption in the kidney?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Which condition can result from prolonged vomiting or diarrhea?
Correct Answer: C
Rationale: The correct answer is C: Dehydration. Prolonged vomiting or diarrhea can lead to significant fluid loss, causing dehydration. Intracellular fluid (choice A) and interstitial fluid (choice B) refer to specific compartments of body fluid and are not conditions resulting from vomiting or diarrhea. Electrolytes (choice D) are minerals that help maintain fluid balance in the body but are not the condition directly resulting from prolonged vomiting or diarrhea.
Question 5 of 5
You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patient's plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to assess what aspect of the patient's health?
Correct Answer: D
Rationale: Assessing the specific gravity in a patient with SIADH helps the nurse evaluate the patient's fluid volume status. Specific gravity indicates the concentration of solutes in the urine and can detect if the patient has a fluid volume deficit or excess. Nutritional status, potassium balance, and calcium balance are not directly assessed through specific gravity testing. Nutritional status is typically evaluated through dietary intake and anthropometric measurements. Potassium balance is assessed through blood tests and ECG monitoring. Calcium balance is evaluated through blood tests and bone density scans. Therefore, the correct answer is assessing fluid volume status through specific gravity testing.
